Totals are the only evidence
Record counts match, but key links or converted fields stay unchecked. The new system looks complete, while staff can't show that its data supports the tasks they need to do.
Data migration
Check your migrated data before you rely on the new system
Records moved, but nobody can show whether the links and values for daily work arrived correctly. Staff keep checking the old system. We check the transfer against agreed criteria and give process owners clear evidence before they rely on it.
Discuss this problemHow We Help
We agree which record types, relationships and business tasks matter before comparing the transfer. Summary counts show coverage, while checks on sample records test values and links. We document expected exclusions separately from defects. We fix confirmed mapping errors within an approved scope, then compare the affected records again. The result supports your acceptance decision. It also explains any reason you must keep access to the old system, including archive or retention needs the new system can't model.
Signs This Is the Problem
Staff still consult the old platform
Routine customer work still means looking up old records. The old platform stays necessary, because nobody has shown that the moved history or relationships are usable in the new system.
Problems emerge through daily use
Missing links and wrong values surface one customer at a time during daily use. Defects turn up piecemeal, instead of being compared in one defined report with clear owners.
What We Investigate
Agree critical validation criteria
We set the key checks with your process owners. Required record types and real tasks define what acceptance needs to show, beyond a successful import or a matching overall count.
Compare record-level mappings
We compare stable references, converted fields and relationship links on sample records. Samples include important exceptions, so a normal customer record doesn't hide gaps in more complex history.
Review exceptions with owners
We review open differences with owners and list expected exclusions separately. Their business impact decides whether a fix, a kept archive or an explicit acceptance exception is needed before routine use.
What We Repair
Build a repeatable validation report
We build a repeatable comparison showing counts, sampled values and critical relationships. Each result keeps safe references to both systems, so your team can see what each result rests on.
Correct verified transfer defects
We fix confirmed mapping or relationship defects and rerun only the approved affected records. The new comparison checks the repaired records without duplicating items that moved correctly earlier.
Support an evidence-based acceptance decision
We record passed criteria and open exceptions for the acceptance decision. We also state any need to keep the old system, including any necessary archive, so it isn't left open only because nobody trusts the transfer.
How We Verify the Fix
- Source and new-system counts match, with documented exclusions, for every required record type.
- Critical customer relationships survive the transfer and support the agreed sample business tasks.
- A reviewed value sample matches the approved transformation and source evidence.
- Process owners can inspect open exceptions before accepting the new system for everyday use.
Questions About This Work
Do matching counts prove success?
No, counts show coverage but can't prove that links and values are correct. We also check sample records and the business tasks they support. A customer total can match even when orders attach to the wrong customer or required notes are missing.
Can the old system be closed afterward?
That depends on accepted exceptions, retention requirements and operating dependencies. Your owners use this evidence to decide when access can change. An archive or another approved way to retrieve records may still be needed for information the new system can't represent.
What if the export is incomplete?
We identify missing source coverage before calling the new system verified. More export access or a kept archive may be necessary. We document the limit, so acceptance doesn't imply that unavailable history moved just because the accessible records arrived.
